Hands-on activity that teaches students everything they need to know about soil. I finally did this activity for the first time today-11/5/13 and it was great. Students actually form Horizon C through the weathering of "bedrock", Horizon A, and Horizon B through "leaching".
Students learn soil horizons, which forms 1st, how they form, soil composition, how living things impact the soil, and many other things related to soil.
Thanks and Enjoy.
